How to empty a composting toilet

The emptying of a TROBOLO is done in a few steps and takes place without you coming into contact with the excretions.

The container for the liquids can be easily removed from the top of the toilet and sealed air- and liquid-tight.

The container for the solids is equipped with an inlay which protects the interior of the solids container from soiling. In order to empty the solids container, you can also remove it from the top of the composting toilet. Fastening the integrated closure renders the container air- and liquid-tight.

Depending on the situation, the containers can then be transported to your own property or over longer distances to get to the emptying location.

How often do I need to empty the TROBOLO?

Thanks to the TROBOLO separation system, a TROBOLO has to be emptied less frequently than a conventional composting or humus toilet. This is due to the fact that a dry toilet is equipped with a collection container in which the human urine is collected together with the faeces (as is the case with a composting or humus toilet) which needs to be bound by litter. On average, one person produces about 550 litres of urine and 60 litres of faeces per year.

The TROBOLO separation system collects the urine in a separate container where it doesn’t need to be bound with litter. Merely the solid excretions are covered with 250ml of litter after every defecation. A TROBOLO with an electric exhaust system doesn’t even require litter as the exhaust system covers the purpose of the litter.

As a result, you have to empty the solids container 10 times less frequently than dry toilets without a separation system. You can find detailed information about the capacity of the various TROBOLO composting toilets on the respective product page under the section ‘Capacity’.

Disposing the toilet waste

We generally recommend two methods to dispose of toilet waste. The first option is the decentralised disposal of toilet waste on your own property. If the conditions for this aren’t given, then the second possibility is to dispose of the toilet waste via your household waste (just like used diapers or the contents of a litter box) and to empty the urine into a toilet that is connected to the sewage system.

If the toilet waste is to be utilised on your own property, you can dispose of it in a composter where it will be composted into useful humus together with other garden waste. It is important to ensure correct composting. To do this, a closed composter should be used to prevent black water developing due to penetrating rainwater. The urine can be diluted with water and used as organic fertiliser when applied in the garden. By returning the human excretions to our natural environment, we’re also giving back essential nutrients and are thereby closing a crucial and ecological cycle.
